Applescript enigma

[dysong3]

I have a series of Applescripts that are incorporated into scripts and that interact with MacBulk Mailer and which worked flawlessly up until FMP 13. Now they generate a series of errors and sort of half work.  However when I run the script from Applescript editor, they are still OK. Here's an example script.

tell application "MaxBulk Mailer.app"
	activate
	SelectList
	"PG"
	AddRecipient
	SaveList
end tell

And here are the error messages I get as it functions.

 

 

 

Would anyone know what's wrong ?
